Rule of Law:
A first-degree murder conviction based on a theory of premeditation and deliberation is supported by sufficient evidence if a rational trier of fact could reasonably infer planning, motive, and a calculated manner of killing from the circumstantial evidence presented.
Facts:
- Defendant Robert Perez and the victim's husband, Michael Mesa, were acquaintances who had attended the same high school approximately ten years prior.
- Perez lived nearby and would drive past the Mesa's house about twice a week, sometimes waving to Michael.
- On the morning of September 30, 1988, Michael Mesa left for work while his four-months-pregnant wife, Victoria Mesa, was still asleep.
- Around 8:05 a.m., a neighbor observed Victoria's car running in the driveway with exhaust coming from it and the front door of the house ajar.
- Victoria Mesa was later found dead in her home from blood loss, having sustained approximately 38 knife wounds from two different knives, as well as blunt force trauma to her face.
- The house showed no signs of forced entry. Perez's blood was found throughout the house, including in a kitchen drawer containing knives. Perez's fingerprint was found on a wall and on a bloody Band-Aid wrapper.
- Around 9:00 a.m. on the day of the murder, Perez arrived at his sister's home appearing pale and sweaty, with a cut on his hand which he claimed was from a saw.
- At 9:20 a.m., Perez sought treatment at a hospital for severe cuts on his hands, telling a nurse he had injured himself with a Skil Saw, a claim the nurse found inconsistent with the wounds.
Procedural Posture:
- The People charged Robert Perez with murder in a California superior court (trial court).
- A jury convicted Perez of first-degree, premeditated and deliberate murder.
- Perez, as appellant, appealed the conviction to the California Court of Appeal.
- A divided Court of Appeal, finding insufficient evidence of premeditation and deliberation, reduced the conviction to second-degree murder.
- The People, as petitioner, sought review from the Supreme Court of California, which was granted.

Issue:
Does sufficient circumstantial evidence of planning, motive, and manner of killing exist to support a jury's finding of premeditation and deliberation for a first-degree murder conviction?
Opinions:
Majority - Panelli, J.
Yes. Sufficient circumstantial evidence exists from which a rational jury could find premeditation and deliberation beyond a reasonable doubt. The court analyzed the evidence using the framework from People v. Anderson, which considers three types of evidence: planning, motive, and manner of killing. The court found evidence of planning in Perez's surreptitious entry into the home and his procurement of a steak knife from the victim's kitchen. A motive could be reasonably inferred: once Victoria, who knew Perez, confronted him, he decided to kill her to prevent her from identifying him. Finally, the manner of killing supported deliberation, as the evidence suggested that after the first knife broke, Perez went back to the kitchen to search for a second weapon, which is akin to reloading a gun and demonstrates a calculated decision to kill rather than a mere rash impulse.
Dissenting - Mosk, J.
No. The evidence is insufficient to support a conviction for first-degree murder because it does not prove premeditation and deliberation beyond a reasonable doubt. The majority's conclusion rests on speculation rather than reasonable inference. The brutal, frenzied nature of the killing, with dozens of wounds but none to a vital organ, is more consistent with a spontaneous, rash explosion of violence than a calculated, preconceived design. There is no substantial evidence of planning prior to the attack, and the witness-elimination motive is a speculative theory that could apply to any murder and does not prove preexisting reflection. This case is factually similar to People v. Anderson, where a brutal killing alone was deemed insufficient to establish premeditation.
Dissenting - Kennard, J.
No. The evidence is insufficient to establish that the murder was committed with premeditation and deliberation. This case is not significantly different from People v. Anderson, as there is no evidence of either planning or a preexisting motive to kill. Furthermore, the manner of the killing does not suggest the careful thought and weighing of considerations that is required to define a premeditated and deliberate murder. Therefore, the conviction should be reduced to second-degree murder.
Analysis:
This case clarifies that the three factors outlined in People v. Anderson (planning, motive, manner) are descriptive guidelines for appellate review, not a rigid, normative checklist for proving premeditation. The decision reinforces a deferential standard of review, affirming that a jury's finding of premeditation will be upheld if it is based on reasonable inferences drawn from circumstantial evidence, even if alternate, innocent inferences could also be drawn. This precedent makes it more challenging for defendants to overturn first-degree murder convictions on appeal by arguing insufficiency of evidence, as it grants considerable weight to the jury's role in interpreting ambiguous facts.
